The invention is an electronically controlled gimbaled platform that is installed on a vehicle. An illumination source mounted on the gimbaled platform provides a steady source of illumination in a desired direction. The desired direction of illumination is initially set and stored in a digital control unit. Subsequently, the digital control unit receives real-time measurements of instantaneous rotations experienced by the vehicle. The digital control unit uses the instantaneous vehicle rotation measurements to compute control signals that compensate for vehicle's movements. The compensatory control signals are communicated to actuators that control the orientation of the gimbaled platform in real-time. The effect of the compensatory control signals is to correct for the dynamic disturbances experienced by the vehicle and thereby provide a steady source of illumination unaffected by changes in the vehicle dynamics. Therefore, the invention facilitates in safer operation of vehicles. |
